Optomec Design Company proposes to use Laser Engineered Net Shaping (LENSTM), a Rapid Prototyping and Manufacturing (RP&M) technology currently under development at Sandia National Laboratories (SNL), as a new method for integrating instrumentation (e.g., embedded sensors) into metal structural components. SNL has demonstrated the ability of the LENSTM technology to produce near net shape stainles ...

Silicon carbide materials will revolutionize semiconductor devices for military and commercial markets. The material's wide bandgap, high electric field breakdown, high thermal conductivity give SiC capabilities that far exceed those of silicon or gallium arsenide. Despite significant progress in silicon carbide development, fundamental defects--most prominently micropipes--persist. If SiC is to s ...

The properties of single-crystal silicon carbide are such that electronics devices from this material have demonstrated remarkable performance characteristics. Despite the material's promise, the material has not yet found acceptance in mainstream device markets because of the material's high cost, among other reasons. This Phase I SBIR proposes an SiC source powder with unique properties which wi ...

Events including the Oklahoma CIty bombing and the Sarin attack in the Tokyo subway have emphasized the vulnerability of personnel, both military and civilian, to unexpected attack with conventional explosives and chemical substances. To combat this threat requires portable, low cost sensor systems capable of detecting a variety of dangerous materials at extremely low concentrations. Such a tech ...

There is a need for simple, light-weight practical instrumentation for rapid characterization of chemical and biological analytes in the modern battlefield. Recently, a surface-sensitive diode laser (SSDL), having over 1% of the mode power in the region extending 40 nm from the laser surface has been designed and fabricated. The SSDL was capable of monitoring the deposition of absorptive films a ...

Microwave resonators of linear dielectrics for wireless applications have been fabricated in bulk form using conventional ceramic processing in the current commercial market. Machining and fine polishing are frequently required for dimension control and surface finish in addition to the inherent unfeasibility to fabricate miniaturized electronic circuits. It is vital to develop a suitable thin f ...

Improved magnetic and electromagnetic sensors covering a wide range of frequencies, 0 to 10kHz, and with extremely high sensitivity are proposed for broad area detection and characterization of underground targets. The sensors can be used for a variety of applications and for different e.m. sources. They can be configured as gradiometers, as vector or scaler sensors and can be used as internette ...

The proof of concept research explores the potential for integrating the following four 'personal devices's () baseline IFF personal device () data applique interface to field processors () audio applique interface to voice headset or audio monitor () video applique interface to camera and display into a single, wearable non-line of sight spread spectrum IFF, tracking and duplex multimedia com ...

Many simulations environments, particularly those used for training purposes, employ simulated human behavior. To date, users frequently complain that such simulated behavior is not very intelligent and easy to "game" thus reducing the effectiveness of the training. We propose to improve intelligent agent technology through improved techniques for eliciting expert problem solving knowledge on wh ...
